NHTSA Complaint #11557913 — 2022 KIA STINGER

Having an issue with my driver’s door switch lighting and the changing of different ambient lighting colors. They seem to be related. About a few months into owning my car (purchased May 2021) I was driving to work at night and the lighting on the driver’s door switches would randomly all flicker off/on. There was no pattern and the duration of how long they were off would be a half second to upwards of a few seconds. Just by chance, I started messing with things in the infotainment screen and noticed my ambient lighting wouldn’t change sometimes and it gave me a body control module error. This has probably happened 7 times total from September 2021 to March 2023 where both the door switch lights and ambient lighting do this together but never have they done it separately. Took the car to VanDevere Kia in November 2021 and they couldn’t reproduce either error and there were no stored codes. They claim to have reset the pin tension on the harness for the switches and packed it with dilectric grease. March 25 2022, had the same issue driving home from work. Restarted the car and that stopped the door switches from flashing. However the infotainment screen said “vehicle system connection is unstable. Please try again later”. Ie., I tried to pick default blue option in ambient lighting, that error would pop up, but if I kept trying blue it would eventually select blue. Some colors would throw the error and some wouldn’t. This time there was no BCM error. Dealer replaced my driver door switch module April 27 2022 due to a short. I didn’t have issues with those lights flickering for 7 months then it came back. In March of 2023, (2) separate times at night I had all interior lights, including instrument cluster lighting, flick off then immediately back on. I have videos and dealer work orders.
